NTT DoCoMo has devised a cellphone-based breathalyzer system that'll let bus, taxi, and truck companies test their drivers remotely to see if they've been boozing it up behind the wheel. The system consists of a small breath-alcohol sensor made by Tanita that's attached to one of DoCoMo's FOMA 3G handsets and, unlike similar offerings from LG which are merely for one's own edification, this one will transmit the results to the driver's boss, who can also make sure there's no cheating going on thanks to the phone's handy videophone function.
